Function polars::export::arrow::io::parquet::read::to_deserializer

pub fn to_deserializer<'a>(
    columns: Vec<(&ColumnChunkMetaData, Vec<u8, Global>), Global>, 
    field: Field, 
    num_rows: usize, 
    chunk_size: Option<usize>
) -> Result<Box<dyn Iterator<Item = Result<Arc<dyn Array + 'static>, ArrowError>> + Send + Sync + 'a, Global>, ArrowError>

This is supported on crate feature io_parquet only.

Converts a vector of columns associated with the parquet field whose name is Field to an iterator of Array, ArrayIter of chunk size chunk_size.
